Subject: [PATCH] eventdev: fix internal port logic in Rx adapter

[ upstream commit d411c4074fe6d90b695f9d9c4982b8c45f2a675d ]

Set the internal_event_port flag when the ethdev-eventdev
packet transfer is implemented in hardware and add a check
for the flag to ignore the connection when setting up the
WRR polling sequence.

Fixes: 9c38b704d280 ("eventdev: add eth Rx adapter implementation")
